What's the difference between a interchangeable lens digital camera and an ordinary digital camera? What excellent interchangeable lens cameras do major manufacturers have on the market at present? Please recommend it. Generally speaking:

1. We call digital cameras with interchangeable lenses SLR (short for single-lens reflex camera), and cameras without interchangeable lenses are called card machines;

2. From the appearance, the SLR camera with lens change is relatively large and heavy, which is inconvenient to carry, while the card machine is small and light, which is convenient to carry;

3. From the usability point of view, SLR is more powerful and has better image quality, so it can be used for creative photography. However, the operation is a little complicated, which requires higher photography skills for users, and is mostly used by professionals and photographers. However, the function of the card machine is relatively simple, the operation is convenient, and the technical requirements for users are not high, which can meet most general travel and family daily photos.

4. From the price point of view, SLR has a large investment, and it is constantly necessary to add and upgrade accessories such as lenses and flashlights, and it is often worried about the lack of money. The card machine is basically in place at one time, and there is no need to spend money and add any accessories.

At present, Nikon and Canon are the best "interchangeable lens cameras" of major manufacturers on the market, ranging from entry level to professional level, with prices ranging from thousands to tens of thousands.
